Abstract
A measuring tool for collecting down hole information, which essentially has a sensor sub including plural data collecting sensors secured at a forward portion of a drilling pipe and a sonde movable in the drilling pipe. Both the sensor sub and sonde employ a set of loop antennas to effect radiocommunication between them to thereby certainly send data detected by means of the sensors to the sonde.
